JP, 2014-083852, A

  With the glass run attached to the sash, it is necessary to ensure that the lip comes in contact with the sash to ensure sealing. For this reason, the longest dimension (maximum height) of the side wall of the glass run is the shortest dimension (minimum size) of the side plate of the sash in the pressing direction of the glass run so that the lip is not separated from the sash due to manufacturing errors of the sash and glass run. It is preferable to set the error range so as to be less than or equal to the height.

  However, if the error range is set as described above, the height of the side plate of the sash becomes excessively high with respect to the height of the side wall of the glass run, and the protrusion amount of the end portion of the side plate of the sash with respect to the end portion of the side wall of the glass run There is a possibility that the protrusion height may become excessive. If the protruding height of the side plate of the sash becomes excessive, the lip may be bent and rolled up from the end of the side plate, and a good contact state with the sash may not be obtained, and the sealing performance may be reduced. In addition, the curling of the lip leads to the deterioration of the appearance.

  In the hollow lip of Patent Document 1, the door window side area of the door window side area and the sash side area opposed to each other across the hollow portion is formed of a sponge material softer than the sash side area. When the amount of protrusion of the end of the side plate of the sash with respect to the end of the side wall is excessive, the lip is bent and turned up due to the deformation of the door window side area. Therefore, as in the case of the solid lip, it is not possible to prevent the decrease in the sealing performance and the appearance.

  Then, this invention aims at provision of the glass run which can prevent the fall of sealing performance and the fall of the appearance on appearance by preventing upset.

  In order to achieve the above object, according to the present invention, first and second sash inner side surfaces spaced apart and opposed in the width direction of the door are defined to define a fitting recess opened along a door window opening of a vehicle door A first and a second sash end surface extending in a direction away from each other from the respective front end edges on the door window side of the first and the second sash inner side surfaces, the sash fixedly provided to the door, An elastic glass run mounted from the side of a door window, comprising a glass run body and first and second lip portions. The glass run main body integrally has opposing first and second glass run side wall portions, and the first and second glass run side walls face the first and second sash inner side surfaces respectively. And fit from the door window side to the fitting recess of the sash. The first and second lip portions extend in the direction away from each other from the respective leading edges of the first and second glass run side wall portions on the door window side.

  In a glass run attachment state in which a glass run body is fitted in the fitting recess, the first and second glass run side walls define a glass entry groove that opens toward the door window to allow the peripheral edge of the window glass to enter, The first and second lip portions respectively face the first and second sash end faces. At least a first lip portion of the first and second lip portions has a sash side lip region facing the first sash end face and a door window side lip region not facing the first sash end face sandwiching a hollow portion It is a hollow shape facing each other. The sash side lip region is formed thinner than the door window side lip region.

  In the above configuration, in the glass run attachment state in which the glass run main body is fitted in the fitting recess, it is necessary to ensure that the first lip portion is in contact with the first sash end face to ensure sealing performance. For this reason, the longest dimension (maximum height) of the first glass run side wall portion in the pressing direction of the glass run so that the first lip portion is separated from the first sash end face and a gap is not generated due to manufacturing errors of the sash and the glass run It is preferable to set an error range so that (a) is equal to or less than the shortest dimension (minimum height) of the first inner surface of the sash.

  When the error range is set as described above, the height of the inner surface of the first sash may become excessively high with respect to the height of the first glass run side wall portion, and the first run in the pressing direction of the glass run When the glass run sidewall has the shortest dimension (minimum height) and the first sash inner side surface has the longest dimension (maximum height), relative to the tip of the glass run sidewall (proximal portion of the first lip) The protrusion amount (projecting height) of the first sash end surface is maximized. Thus, there is a possibility that the projecting height of the first sash end face becomes excessive, but the first lip portion faces the sash side lip region facing the first sash end face and the first sash end face Since the sash side lip region is formed thinner than the door window side lip region, the projection height of the first sash end face is the hollow shape where the sash side lip region is formed to be thinner than the door window side lip region. Even when it becomes excessive, in a state where the elastic deformation of the door window side lip area is suppressed, the sash side lip area is elastically deformed flexibly and the protrusion of the first sash end face is favorably absorbed. For this reason, it is possible to prevent the lowering of the sealing property and the lowering of the appearance on the appearance due to the first lip portion being bent and rolled up from the front end portion of the first glass run side wall portion.

  In addition, the sash side lip region in the glass run attachment state may be pressed by the first sash end face to be elastically deformed.

  In the above configuration, the sash side lip region in the glass run attachment state is pressed by the first sash end face to be elastically deformed. That is, even if the first glass run side wall portion has the maximum height within the error range and the first sash inner side surface has the minimum height within the error range, the first lip portion has the first height. Contact the sash end face. Therefore, the first lip portion and the first sash end face can be more reliably sealed, and the sealing performance is improved.

  ADVANTAGE OF THE INVENTION According to this invention, the fall of sealing performance and the appearance fall can be prevented by preventing upswing.

And the door window side lip region 59 not facing each other. A hollow portion 60 is provided between the sash side lip region 58 and the door window side lip region 59 of the door inner side engagement lip portion 57a and the door outer side engagement lip portion 57b. The sash side lip region 58 is formed thinner than the door window side lip region 59.

  On the inner side of the door inner engagement lip portion 57a, an outer wall portion 61 extending from the end of the inner side of the door to the sash portion 33 is provided. Between the door inner glass run side wall 52a and the outer wall 61 of the glass run main body 50, a groove-like recess 62 opened toward the sash 33 is formed. The door inner engaging plate portion 35a is engaged with the groove-like recess 62 from the sash portion 33 side in a glass run attachment state. The depth of the groove of the groove-like concave portion 62 is substantially the same as the protruding height of the door inner engagement plate portion 35a. In the present embodiment, the outer wall 61 is formed on the inner side of the door inner engagement lip 57a so as to extend from the inner end of the door to the sash 33. However, the present invention is not limited thereto. It is not a thing. For example, as shown in FIG. 5, a door inner sash end surface 71a extending to the inside of the door is provided at the tip edge of the door inner engaging plate 70a on the door window 4 side, and the door window with the door inner glass run side wall 72a. The door inner engagement lip portion 73a extends from the front end edge of each of the four sides to the inside of the door, and the sash side lip region 74a inside the door is elastically deformed by being pressed against the door inner sash end face 71a It is also good.

  In the glass run attachment state, the fitting protrusion 53 linearly extends along the fitting recess 34, and the door inner glass run side wall 52a and the door outer glass run side wall 52b define the glass entry recess 54, and the sash side of the door inner The lip region 58a is pressed against the door inner sash end surface 37a to be elastically deformed, and the door outer sash side lip region 58b is pressed against the door outer sash end surface 37b to be elastically deformed. The door window side lip region 59b on the outside of the door is continuous with the side surface of the side plate portion on the outside of the vehicle compartment with the glass run mounted.

  In the glass run 8 configured as described above, the longest dimension (maximum height) of the door inner glass run side wall 52a and the door outer glass run side wall 52b in the pushing direction of the glass run 8 is the door inner sash inner side 36a and the door outer sash An error range of manufacturing errors of the sash portion 33 and the glass run 8 is set so as to be equal to or less than the shortest dimension (minimum height) of the inner side surface 36b. Therefore, in the glass run attachment state, the door inner engagement lip portion 57a and the door outer engagement lip portion 57b reliably contact the door inner sash end surface 37a and the door outer sash end surface 37b, so that sealing performance can be ensured. .

  If the error range is set as described above, the height of the door inner sash inner side surface 36a becomes excessively high with respect to the height of the door inner glass run side wall 52a, and the protruding height of the door inner sash end surface 37a becomes excessive. The possibility arises. Even if the projecting height of the door inner sash end surface 37a is excessive, the door inner engaging lip portion 57a has a hollow shape, and the sash side lip region 58a of the door inner side is the door window side lip of the door inner side. Since it is thinner than the area 59a, the sash side lip area 58a inside the door is elastically deformed flexibly in a state where the elastic deformation of the door window side lip area 59a inside the door is suppressed, and the door inside sash end face The protrusion of 37a can be absorbed well.

  Therefore, the sealing performance is deteriorated or the appearance is deteriorated by bending and rolling up the door inner engagement lip 57a and the door outer engagement lip 57b from the tips of the door inner glass run side wall 52a and the door outer glass run side wall 52b. It is possible to prevent the deterioration of the appearance.

  In addition, the sash side lip areas 58a and 58b of the door inner side and the door outer side in the glass run mounted state are pressed by the door inner sash end face 37a and the door outer sash end face 37b to be elastically deformed. That is, the door inner glass run side wall 52a and the door outer glass run side wall 52b have the maximum height within the error range, and the door inner sash inner side 36a and the door outer sash inner side 36b have the minimum height within the error range. Even in this case, the door inner engagement lip portion 57a and the door outer engagement lip portion 57b contact the door inner sash end surface 37a and the door outer sash end surface 37b. Therefore, the seal between the door inner engagement lip 57a and the door outer engagement lip 57b and the door inner sash end surface 37a and the door outer sash end surface 37b can be more reliably sealed, and the sealing performance is improved.
